Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 500mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A
The SAUF32X500-08A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The compact profile is shorter than an ISO 15552 cylinder of the same bore. This 32mm bore unit has a 1/8 inch cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 402N push at 0.5MPa. The integrated 4M210-08 valve features a 1/4 inch port, Cv 0.89 flow, and 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 241N (60% of the 402N figure), yielding a 20kg vertical lift capacity with a 2:1 margin. Note this SKU lacks the S magnet suffix and cannot accept a magnetic switch.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A Is Used
Decentralized Forming Press
Ideal for a large press needing one valve per actuator, using the 4M210 valve to switch locally without a central manifold.
Sorting Diverter Gate
Perfect for a 500mm diverter on a conveyor, saving tubing by mounting the AC220V valve directly on the cylinder cap.
Vertical Lift Station
Handles a 20kg vertical lift with a 2:1 margin at 0.5MPa, fitting decentralized packaging lines with minimal plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A the Right Choice?
Size by checking both neighboring bores and the 0.5MPa force: this 32mm bore pushes 402N, while the 40mm bore pushes 628N. Confirm the AC220V terminal entry coil and PT threads match your supply. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa operating range. By default the rod retracts when energized; reposition the valve to extend on signal. The valve routes air and is not a load lock, so add an external rod lock or pilot-operated check valve to hold loads. For this 500mm stroke, use external guides to prevent rod bending and side loads. Mounting uses AirTAC SC series accessories.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4 inch port, Cv 0.89, 5 cycles/sec) with an AC220V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised; you can reposition the valve to extend on signal. The valve only routes air, so it is not a load lock. The piston drifts on air loss, requiring an external rod lock or pilot-operated check valve to hold a load.
